Sir Henry Rawlinson's view was shared by M. Oppert, Professor Schrader, Professor Sayce, and many others, and, in fact, it held the field until a theory was propounded by M. Halévy to the effect that Sumerian was not a language in the legitimate sense of the term. The contention of M. Halévy was that the Sumerian compositions were not written in the language of an earlier race, but represented a cabalistic method of writing, invented and employed by the Babylonian priesthood. In his opinion the texts were Semitic compositions, though written according to a secret system or code, and they could only have been read by a priest who had the key and had studied the jealously guarded formulæ. On this hypothesis it followed that the Babylonians and Assyrians were never preceded by a non-Semitic race in Babylonia, and all Babylonian civilization was consequently to be traced to a Semitic origin. The attractions which such a view would have for those interested in ascribing so great an achievement to a Semitic source are obvious, and, in spite of its general improbability, M. Halévy won over many converts to his theory, among others Professor Delitzsch and a considerable number of the younger school of German critics. It may be noted that the principal support for the theory was derived from an examination of the phonetic values of the Sumerian signs. Many of these, it was correctly pointed out, were obviously derived from Semitic equivalents, and M. Halévy and his followers forthwith inferred that the whole language was an artificial invention of the Babylonian priests. Why the priests should have taken the trouble to invent so complicated a method of writing was not clear, and no adequate reason could be assigned for such a course. On the contrary, it was shown that the subject-matter of the Sumerian compositions was not of a nature to justify or suggest the necessity of recording them by means of a secret method of writing. A study of the Sumerian texts with the help of the Assyrian translations made it obvious that they merely consisted of incantations, hymns, and prayers, precisely similar to other compositions written in the common tongue of the Babylonians and Assyrians, and thus capable of being read and understood by any scribe acquainted with the ordinary Assyrian or Babylonian character.
